2009 European Workshop on GNSS Signals and Signal Processing Issues Call for Papers

Open House at the German Aerospace Center (DLR) near Munich, Germany.

GNSS Signals 2009 will take place at the German Aerospace Center (DLR) in Oberpfaffenhofen, Germany on Thursday and Friday, December 10-11 2009.

The free workshop will cover recent advances in GNSS signal design,
evolution of Galileo and other GNSSes and a number of GNSS signal processing and observation techniques. The presentations and papers will be in English. 

Program committee cochair Jean-Luc Issler of CNES, the French space agency, said the first call for papers has gone out and abstracts are due before October 2, 2009.

A new Compass signal and frequency plan introduced at a recent International Committee on GNSS (ICG) working group meeting fills in some of the gaps on China’s current thinking about its GNSS system.

The presentation on the new Compass (Beidou-2) plan came at a July
30–31 workshop of the ICG Working Group A – Compatibility and
Interoperability (WG-A), in Vienna.

Ready, Set, Go! The 2009 European Satellite Navigation Competition is open for ideas

Galileo Master’s award winners 2008

Submit the best idea for a brand new satellite navigation application or device and you just might win the 2009 Galileo Master’s Award – €20,000 in prize money and lots of support to make your idea a reality.

But that’s not your only chance – you can try for one of the eight special topic prizes or one of the 17 different regional prizes, together worth €500,000 in cash and start-up assistance.

The competition began six years ago in Bavaria, Germany, but it has expanded to include many other regions of Europe as well as Australia, Israel, and Taiwan.

Highlights of the 2009 Munich Satellite Navigation Summit (March 3- 5): Russia will place its first CDMA signal on the GLONASS L3 frequency that overlaps the European Galileo E5b spectrum; China plans to launch three Compass satellites this year and seven more next year to provide a regional capability for Compass/Beidou, followed by completion of the full 30-MEO, 5-GEO constellation after 2015 and before 2020; Galileo program discussions revealed tensions around negotiations with China about a frequency overlay of Compass signals on the security-oriented Public Regulated Service as well as the question of whether the costs to build Galileo can be kept within the €3.4-billion limit agreed by the European Council and the European Parliament; the GPS Block IIR-20(M) satellite with an L5 demonstration payload will be launched later this month in what may be the program’s last chance to secure primary GPS access to the frequency.

GNSS Vulnerabilities and Solutions Conference 2009

The 2009 GNSS conference will focus on problems and vulnerabilities, and in particular, on developments aiming to improve the accuracy and reliability of the various GNSSes. It will take place on the resort island of Krk during the Adriatic high season.

Two special sessions will be organised in order to address particular causes of GNSS vulnerabilities: Space Weather and Ionospheric Effects on GNSS, and Safety Critical Applications (concerning primarily the ITS).

Satellite Collision Raises Issue of Similar GNSS Risks

Satellite Collision Raises Issue of Similar GNSS Risks

GPS Orbital Decay. Aerospace Corporation

The February 10 collision of an active Iridium satellite and a defunct Russian military communications satellite underlines a concern raised recently at the International Committee on GNSS (ICG) about the need to include coordination of space vehicle (SV) operations.

In comments during a session of Working Group A (compatibility and interoperability) during the ICG’s recent meeting in Pasadena, California, Professor Grigory Stupak of the Russian Institute for Space Device Engineering (RISDE), noted that Russia’s “position is that compatibility includes more than just signals,” among other things, “the sharing of orbits and disposal of satellites.”

Similar concerns have been expressed in recent years by organizations that have studied the possibility of GNSS satellites, particularly those that have been “parked” in disposal or graveyard orbits, to drift and possibly collide with one another.
